At 0.5 A, a 22 Ah battery would be good for 22 hours on the basis that these types of batteries should not be discharged to more than 50% pf their capacity.

?

22 Ah*50%/0.5A? = 22 hours

I have had good luck with Power-Sonic SLAs (I have 3).? This is a link to their 12V series.

yes, they will definitely work.?

?

Car starter batteries are more designed around offering a maximum amperage to kick over the motor.?

?

for astro that's not important -? instead we want greater battery capacity, hence amp-hours

?

if your losmandy pulls .5a then a 22 amp-hour will last about 11 hours, or pretty much all night long

?

?

me, I power my losmandy G11T, intel nuc i5 computer, focuser, dew heater, camera, guide camera, and whatever USB junk is connected to my computer. so my amp-hour usage is a lot more.

?

just FYI
